★★★★★ Verified Buyer – Senior Industrial HVAC Engineer

"Outstanding German quality from ZIEHL-ABEGG. The MK137-4DK.20.U runs incredibly quiet at both 1410 and 1710rpm while delivering massive centrifugal airflow. The dual-speed 1.96kW motor provides excellent energy flexibility – we use lower speed for overnight cooling and higher speed for peak industrial demand. Build quality is exceptional at 21kg, clearly designed for 10+ years of heavy-duty service. Perfect for our large-scale ventilation system. Highly recommended for any demanding industrial application."

Inexpensive Solution For Privacy
Color: Grey, Size: 2 Large Panels, Color: Grey, Size: 2 Large Panels
This worked for my needs to get privacy on a second-floor patio that faced neighbors about 16 feet away, and was almost exactly the width and height I need, and was looking for. As the patio was about 12 feet in width. The fabric is thin, but not see-through, and works well enough for my specific privacy needs. It wasn't that sturdy, even with the three legs, the top would kind of bend a bit from the weight of the thing, but I knew this from previous comments on reviews, and opted to use C-clamps and some screws to tighten it to the wall so that isn't an issue since I was outside and had walls to be able to screw into. You may have to try something different if using inside. I gave four stars instead of five as the instructions past Step 3 really don't make much sense for Steps 4 and 5 where the two are connected and when legs are put on, but I was able to work through it eventually. They really need to break down the steps for installing the legs with better illustrations. Also, highly recommend having two people work on it or at least having a second person on standby for certain steps just due to the size of them once they are together or for connecting the dividers together in the end.

Very sturdy & nice looking! Impressive & functional
Color: Black, Size: 2 Large Panels, Color: Black, Size: 2 Large Panels
I needed to divide our living room room in half and create a work room but didn’t want it to be visible so we decided to get this and use it in an L shape. It’s very simple and functional, but it does exactly what I need. I’m contemplating hanging a photograph from a ribbon just to add a little personality to the side that faces the living room room but honestly, it’s much more sturdy than I gave a credit for. I am a full-time reseller so I got foam from the hardware store and covered it in fabric as a background for taking pictures and I have a huge one that’s 6‘ x 3‘ plus another one that’s 4‘ x 4‘ both of which are hanging on the inside of this and it works great. I’m impressed!!

Weigh your options
Color: Grey, Size: 2 Large Panels
It serves the purpose but make sure you stabilize it. It's not a bad product it's extremely light and insecure without something to hold the base in place. Maybe it was just the one I bought but it moved a lotI would just bump it a little and it would fall over. The good thing is It is easy to set up and has versatile usage. Also it's really big. Takes up a lot of space make sure you measure your room first.

Functional not durable
Color: Grey, Size: 1 Large Panel
When first assembled, it looked exactly like the picture. However, over time, the top bar has begun to bow. The metal bars are weaker than I expected. It is still doing it's job providing privacy but the quality is not quite up to par. The height, color, and functionality are all exactly as described. If you need an inexpensive room divider, this is a great option. I don't expect it to last more than a year or two, but I would still recommend this product for those needing something fast, easy to assemble, and don't need for an extended period of time.
